Embodiments of the present invention disclose a method, an apparatus, and a system for transmission control of multimedia broadcast multicast data. The method includes: according to a reference time, determining a scheduling period of suspending or resuming sending MBMS service data; and suspending or resuming sending the MBMS service data in the determined scheduling period. According to the embodiments of the present invention, transmission control of the MBMS service data by a base station can be realized, which facilitates each base station in the same MBSFA range synchronously suspending or resuming sending the MBMS service data of the same service, thereby facilitating reducing interferences in the service
